1) OS command injection (CVE-ID: CVE-2017-9800)
CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The weakness exists due to command injection flaw. A remote attacker (e.g., repository, proxy server) can return a specially crafted 'svn+ssh://' URL during 'checkout', 'export', 'update', and 'switch' commands and execute arbitrary shell commands with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
